It serves to hold the heart in place within the mediastinum and protects it from infection and blunt trauma, while also lubricating its movement.

Which of the following best describes the function of the bladder?

Answer: To store urine until urination occurs.

Related Concepts:

  • What is the function of the bladder?: The bladder is a hollow, muscular organ that stores urine. When it is full, signals are sent to the brain, which then allows the urinary sphincter to relax, enabling urination.

Which of the following is a key risk factor for coronary artery disease mentioned in the source?

Answer: High cholesterol

Related Concepts:

  • What is coronary artery disease, and what are its major risk factors?: Coronary artery disease is a condition where plaque builds up in the coronary arteries supplying the heart, restricting blood flow. Major risk factors include obesity, smoking, high cholesterol, high blood pressure, lack of exercise, and diabetes.

The source states that the nervous system has functional divisions. Which division controls voluntary actions?

Answer: Somatic Nervous System (SNS)

Related Concepts:

  • What are the functional divisions of the nervous system?: Functionally, the nervous system is divided into the somatic nervous system (SNS), which controls voluntary actions and sensory processes, and the autonomic nervous system (ANS), which regulates involuntary processes like digestion and blood pressure.

How does the source describe the relationship between the lymphatic and circulatory systems?

Answer: They are similar in transporting body fluid and play roles in immunity.

Related Concepts:

  • How is the lymphatic system similar to the circulatory system?: The lymphatic system is similar to the circulatory system in both its structure and its fundamental function of transporting body fluid. It plays a vital role in fluid balance, immunity, and fat absorption.

Homeostasis and Bodily Regulation

Homeostasis refers to the process by which the body maintains a stable internal environment.

Answer: True

Related Concepts:

  • How does the human body maintain a stable internal environment?: The human body maintains a stable internal state, known as homeostasis, through the interaction of its various systems and mechanisms. This involves keeping essential substances like sugar and oxygen in the blood within safe levels.
  • What is human physiology, and what is its central concept?: Human physiology is the study of how the human body functions, encompassing mechanical, physical, bioelectrical, and biochemical processes. A central concept in physiology is homeostasis, the maintenance of a stable internal environment.

The nervous and endocrine systems work independently, with no interaction in regulating the body.

Answer: False

Related Concepts:

  • How do the nervous and endocrine systems interact to regulate the body?: The nervous and endocrine systems work together as the neuroendocrine system. The nervous system transmits rapid signals via nerve impulses, while the endocrine system uses slower-acting hormones to regulate processes like blood pressure and metabolism, collectively maintaining the body's internal balance.

The maintenance of a stable internal environment within the human body is known as:

Human Development and Reproduction

Sperm cells are finite in number and are present from birth in males.

Answer: False

Related Concepts:

  • How does sperm production differ from egg cell production in humans?: Unlike the finite number of egg cells present at birth in females, sperm cells are continuously produced throughout a male's life after puberty begins.

Human development begins with the formation of tissues from specialized cells.

Answer: False

Related Concepts:

  • What is the process of human development from fertilization to birth?: Human development begins with fertilization, where a sperm penetrates an egg. The resulting zygote implants in the uterus, developing into an embryo and then a fetus until birth. This process is influenced by genetic, hormonal, and environmental factors.

The primary purpose of the reproductive system is to maintain the body's internal fluid balance.

Answer: False

Related Concepts:

  • What is the primary purpose of the reproductive system?: The primary purpose of the reproductive system is to enable reproduction and support the development of offspring. This involves the production of germ cells (sperm and eggs) and sex hormones.

Female puberty typically begins earlier than male puberty, around ages 9 to 13.

Answer: True

Related Concepts:

  • How does female puberty differ from male puberty in terms of development?: Female puberty, typically occurring between ages 9 and 13, involves ovulation, menstruation, and the development of secondary sex characteristics like breast growth and hip widening. Male puberty is characterized by the further development of the penis and testicles.

How does sperm production differ from egg cell production in humans, according to the source?

Answer: Sperm are produced continuously after puberty; eggs are finite from birth.

Claude Bernard is known for describing the process of homeostasis in the human body.

Answer: False

Related Concepts:

  • What key concept did Claude Bernard introduce in physiology, and who later expanded on it?: Claude Bernard introduced the concept of the 'milieu interieur' (internal environment) in physiology. Walter Cannon later built upon this concept, describing it as homeostasis, the process of maintaining a stable internal state.
